contactless working transponder or smart labels are state of the art. Such devices have no electrical connections and are able to contactlessly exchange data with their environment. Therefor is on or in the smart label a large coil of several turns applied and a chip module present, which controls the data communication. To operate a smart label generates a reader in one there existing conductor loop or coil with several turns a high-frequency magnetic field. Is the reading antenna of the Smart labels nearby In this field, the field of the reader becomes one Voltage generated in the coil and rectified, which as a power supply for the Smart label is used. Therefor In practice, on the label side, an inductance is connected in parallel, so that a parallel oscillating circle is created, whose resonance frequency on the Transmitter frequency is tuned.

Out the induced in the smart label antenna coil AC voltage then becomes additional for the chip module derived in the label a system clock, so that command-oriented then a transmission of Information stored in the label is read out to the reader can be. The data transmission itself can be bidirectional.

reaches So a transponder label in the range of a read / write station, Thus, in the case of the passive transponders described above, the Energy storage of the same charged. The transponder then transmits then the contents of its data memory to the read / write station and / or receives from this new data. The data security during the transmission is by a corresponding Data log given. This also makes it possible to have several within reach read the transponder located in the read / write station or to describe.

The Range of data transmission depends on of the antenna size of the transponder, the Performance of the read / write station and the transponder type. According to the ISO standard 15693 are properties of transponder labels or smart cards contactless design with a range of up to one meter To be defined. In this standard is also the uniform transmission frequency for radio applications small power of 13.56 MHz.

by virtue of the fact that transponder or smart labels have no line of sight need to read station, can this diverse be used. If new information is brought in due to the situation or changed Need to become, this can be done easily with a transponder. For the purpose of quality assurance exists the possibility, after each production step a clear identification in the Store memory of the transponder. This also allows for subsequent prosecution production routes, e.g. Sources of error within a production or processing process.

Accordingly, in Difference to previously only in-house executed arrangements now the Attachment of the transponder label only punctiform cohesively made the inside of the tire. This is preferred in the center of the area or in the center of gravity of the transponder label a recess, e.g. introduced by punching. A standard transponder label, which with is provided such a punch, is then in the tire bed inserted. With the aid of a fixing liquid, e.g. vulcanizing, is then formed by the punching in the transponder label through a bridge, which is to be completed with a button-like holding element upwards.

By this briefly explained above Mounting arrangement becomes the label of the walking zones of the tire disconnected, leaving the antenna coil and the chip module, which are in defined areas of the label, no longer directly from the powers, especially forces due to the flexing of the tire.

The above the mounting bridge provided, the recess in the label overlapping support surface has prefers a button or mushroom head shape and can be made of a rubber or rubber-like material.

Also is preferably provided that the mounting bridge itself made of rubber or a rubber-like material.

As already indicated, is the preferred transponder label a standard RFID label, which is an additional hole punching or recess includes.

at an embodiment The invention is the punctiform Attachment of the transponder label on the inside of the tire with a square film carrier structure with chip module located in a corner region of the structure provided in this corner area. Again, the punctiform attachment ensures that force effects declining on the typical use of a tire not or only slightly Dimensions on the transponder label and the active and passive electronic components located there can act.

the method, is used to fabricate the wireless identification device as well as for the logistical pursuit of the life and employment cycle of Tires, in particular motor vehicle tires, by means of at least one Transponder or smart label first in the transponder label a recess, preferably introduced by punching. In connection This is the thus provided with a punched transponder label inserted in the tire bed.
